I’ve corresponded with Thomas J. Ryan a few times over the years, enough to know he’s been working on Spies, Scouts, and Secrets in the Gettysburg Campaign: How the Critical Role of Intelligence Impacted the Outcome of Lee’s Invasion of the North, June-July 1863 (Savas Beatie) for a long, long time. Tom is well suited to the topic, having worked for the Department of Defense in intelligence related areas for many years.
In this new study, Ryan looks at how the opponents in the campaign used various sources (cavalry, newspapers, civilians, and spies for Lee, and cavalry, signal corps, and Bureau of Military Intelligence for Hooker/Meade) to guide them in the theater of operations. After laying out the assets and structures of the armies, the narrative follows a chronological path, from mid-May 1863 through Lee’s “escape” July 14, and concludes with the author’s assessment.
Spies, Scouts, and Secrets… consists of 448 pages of text, a 15 page bibliography, full index, and footnotes on the text pages. There are plenty of illustrations, including 23 (!) Phil Laino maps. I’m looking forward to digging in. Check out Tom Ryan’s website here.
